the sika, it's not required but some do it. the important thing is eating and sharing of meals, because that is the basic activity we do in our homes. one of the things that we do is take what we call the four species, which is a palm branch, sprigs of willows, sprigs of myrtle and a creditron that loo like a large lemon. we hold all four and wave them and smell them and hear them. that gives us a nice feeling of being alive and in touch with our senses. five days ago on yom kippur, the day of atonement, we denied ourselves any sensory experiences. everything was thinking, sitting, and praying. sikut is just the opposite. it's an indulging of the senses.
